The following sections outline a _reasonable_ style guide for modern JavaScript development and are not meant to be prescriptive. The most important take-away is the **law of code style consistency**. Whatever you choose as the style for your project should be considered law. Link to this document as a statement of your project's commitment to code style consistency, readability and maintainability.

1. <a name="whitespace">Whitespace</a>

- Never mix spaces and tabs.

- When beginning a project, before you write any code, choose between soft indents (spaces) or real tabs, consider this **law**.

- For readability, I always recommend setting your editor's indent size to two characters &mdash; this means two spaces or two spaces representing a real tab.

- If your editor supports it, always work with the "show invisibles" setting turned on. The benefits of this practice are:

- Enforced consistency

- Eliminating end of line whitespace

- Eliminating blank line whitespace

- Commits and diffs that are easier to read

- Use [Editorconfig](http://editorconfig.org/) when possible. It supports most IDEs and handles most whitespace settings.
